This book clearly examines how to create the best astronomical images possible with a digital camera. It reveals the astonishing images that can be obtained with simple equipment, the right software, and knowledge of how to use it.

Digital electronic imaging devices, like the CCD, and more recently inexpensive webcams, allow the wonders of the universe to be seen in detail never before possible from an amateur astronomer's backyard. As a result, more amateur astronomers becoming involved in digital imaging. This book clearly examines how to create the best astronomical images possible with a digital camera. It reveals the astonishing images that can be obtained with simple equipment, the right software, and knowledge of how to use it. Completely jargon-free, the book describes how to extract results from the raw-and-dirty original imagery and then transform them into high-quality pictures suitable for framing, posting online, or sharing with friends and colleagues.

Written by one of the world's professional experts in image processing Explanations that clarify the jargon (with box-outs where necessary) Non-mathematical approach Illustrated examples of an image processing session Illustrated examples (in colour and monochrome) State-of-the-art techniques with various software packages Includes supplementary material: sn.pub/extras

Klappentext

Digital imaging is now available to all amateur astronomers at a reasonable price. The advent of CCDs, DSLRs and perhaps most significantly webcams mean today's astronomers can make colorful planetary or deep-sky images of breathtaking beauty. The results obtained with even modest equipment can be spectacular, but of course they depend crucially on the computer processing of the images after they have been captured. Enhancing Digital Images is not just an introduction to image processing, it is a deeply practical, comprehensive and fully illustrated in-depth guide to using a digital camera, performing image reduction and undertaking image enhancement all without jargon or math. Here is everything you need to know about processing digital astronomical images, regardless of whether you are experienced or a relative beginner!
